论文摘要
在$ d_s^{* - } d^0 $和$ d_s^{ - } d^{*0} $ Channel添加了重要的动态信息，以对$ d_s^{* - } d^0 $和$ d_s^{*0} $观察$ z_ {cs}（3985）$。 $ z_ {cs}（3985）$和$ z_ {cs}（4120）$，基于重质量旋转对称性。在SU（3）风味对称性中，我们表明可以从实验数据中提取极点结构。同时，我们展示了$ s $ - 波开放阈值在$ e^+e^ - $ nihiliations中发挥的关键作用，这些阈值与Hadronic分子图片中这些$ z $状态的生产相关。他们的标量重夸克旋转伙伴的含义也获得了$ w_ {c0,1,2} $和$ w_ {cs0,1,2} $。
The observation of $Z_{cs}(3985)$ by BESIII in the $D_s^{*-}D^0$ and $D_s^{-}D^{*0}$ channel adds important dynamic information for a coherent understanding of both $Z_c(3900)$ and $Z_c(4020)$, as well as their strange partners $Z_{cs}(3985)$ and $Z_{cs}(4120)$, on the basis of heavy quark spin symmetry. With an overall short-ranged contact potential in SU(3) flavor symmetry we show that the pole structures can be extracted from the experimental data. Meanwhile, we show the key role played by the $S$-wave open thresholds in $e^+e^-$ annihilations which are correlated with the production of these $Z$ states in a hadronic molecule picture. Implications of their scalar heavy quark spin partners $W_{c0,1,2}$ and $W_{cs0,1,2}$ are also gained.
